Leaded Gunmetal Bronze Hollow Round Bar LG2 Imperial

• LG2 Bronze is one of the most used grades of bronze in the industry.
• Has medium strength, excellent machining properties, and is suitable for bearings, gears, and other components used in relatively light-duty applications.
• Although LG2 is often referred to as phosphor bronze, it is in fact leaded gunmetal. Only the “PB" group of bronzes (PB1, PB2, etc) can truly be called phosphor bronze.
• PB1 Bronze Bar is also available. Contact AIMS for assistance.
• Manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength are superior to sand-casting methods.
• This also means that the material has a fine grain structure and is free from porosity.
• Available in various sizes.

Machining Allowances

• LG2 Bronze bar has machining allowances added to the sizes quoted.
• To use a 4-1/2" x 2-1/2" hollow bar as an example, this material would measure approximately 4.570" OD x 2.440" ID as supplied (see table below).
• Therefore this allows finished components measuring 4-1/2" OD x 2-1/2" ID to be easily manufactured from 4-1/2" x 2-1/2" hollow bar.
